City Life is a real-time strategy game that lets the player create a modern city. It is the first modern city-building game to allow the player to work in full 3D environment. The game is by French developer Monte Cristo. It is published in France by Focus, in the UK and Germany by Deep Silver and in North America by CDV. It was released in May 2006.

City Life allows players to zoom in and see every little bit of detail. The placement method allows buildings to be placed at an angle, as also seen in Sierra Games' Caesar IV.

More recently, the game has been criticized for lack of many detailed elements, such as weather, disasters, and more "in depth" user control.

From superb villas in residential neighbourhoods to imposing skyscrapers in the financial district, design, construct and develop the city of your dreams. Provide comfort and satisfaction for your citizens by offering them work, health care, entertainment facilities, and much more and ensure that your city’s coffers are brimming. It’s up to you to manage this city efficiently, ensuring booming development while at the same time regulating the very delicate issues of pollution and traffic. Let peace reign between the six unique subcultures, or pay the price if the situation deteriorates into conflict, riots, and, in the worst-case scenario, fires.
